IMPROVEMENT IN REVERSIBLE PLCfW POlNTS.

Specification forming part of Letters Patent No. 65,703, dated July20,1875; application filed December 19, 1874.

To all whom it may concern:

Be it known that l, .MAROUS M. Bownas, of Richmond, in the county ofHenrioo and State of Virginia, have invented a new and use ulImprovement in Reversible Plow-Point, of which the following is aspecification:

Figure l is a top view of a plowshare to which my improved reversiblepoint has been applied. Fig. 2 is a cross-section of the same takenthrough the line at a}, Fig.1. Fig. 3 is a perspective view of thereversible point detached.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved detachable andreversible plowpoint, which shall be so constructed that it may beconveniently detached and reversed without changing its line and set,and which may be readily cast without changing the ordinary patterns,and shall be strong, durable, and not'liable to become loose or dropout.

The invention consists in a detachable and reversible plow-point, madewith lips upon the upper and lower edges of the sides of its shank,whether said shank be made tapering orwith parallel sides.

A is the plowshare, in the forward angle or corner of which is formed avertical socket, a,

which may be made tapering, as shown in Fig. 1, or with parallel sides,as may be desired. The upper and lower edges of the socket a are beveledoff, as shown in Fig. 2, and the outer sides of the angle or corner ofthe share A are beveled ofi, as shown in Fig. 2. B is the point, whichis made with a shank, N, of such ashape and size as to fit into thesocket a, and with lips at the edges of its sides to fit into the bevelsof the socket a, and thus keep the point B in line. The point Bis alsomade with inclined shoulders 1) upon its sides, at the base of itsshank, to fit upon the bevels of the end of the share A, as shown inFig. 1.

The inclined shoulders I) prevent the parts of the share A upon thesides of the socket a from spreading, and making the point loose.

The points B are made exactly alike upon the upper and lower sides, sothat it may have the same line and set whichever side be up.

The points B may be cast or forged, as may be desired.

The sockets a may be cast in the shares A by using the ordinaryshare-patterns, by inserting a pattern of the point B in the point ofthe mold, and casting the share upon it, the said patterns beingafterward knocked out.

A notch may be formed in the lips of the shank b upon each side of thesaid shank, and a corresponding notch in the side of the socket to, sothat the point may be locked in place by driving a pin or a piece of anail into said notches. This locking will not be required except inspecial cases, as, for instance, when plowing stumpy ground.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A detachable and reversible plow-point, I made withlips upon the upper and lower edges of the sides of its shank b whethersaid shank be made tapering or with parallel sides, substantially asherein shown and de-' scribed.
